Different types of chemical analyses can provide valuable information in corrosion monitoring programs. The measurement of pH, conductivity, dissolved oxygen, metallic and other ion concentrations, water alkalinity, concentration of suspended solids, inhibitor concentrations and scaling indices all fall within this domain. Several of these measurements can be made on-line using appropriate sensors. In many situations, process status and product quality are determined by using chemical methods for which advanced and automated systems for chemical analysis are used.
